To all whom it may concern: .y

Be it known that I, ETIENNE WITZBERCER, a citizen of the United States, residing at Glendale, Carnegie, in the county of AlleA gheny and State of Pennsylvania, have vented new and useful Improvements in Movable Reflector Heaters, of which the following is a specification, i

This invention relates to heatingdevices,

and more particularly to what T term a movable reflector heater.

One of the main objects of the invention is to provide a heater having a movable reflector by means of which the heat is uniformly distributedl through the room or apartment to be heated. A further obyect is to provide a heater including a fireback andv means for causing air to circulate through the fireback so as to be heated thereby, this heated air being distributed by the reflector,v

the circulation of air through the fireback serving to prevent overheating thjeieofand also permitting the heat which is retained by the lireback, after the heater is extinguishechto ybe utilized to advantage. Fur- Figure 4 is a fragmentary detail back viewy of the reflector mounting;

rFigure 5 is a detail `of the means for reciprocating the reflector operating rod;

Figure 6 is a horizontal sectional view;

Figure 7 is a fragmentary sectional view taken substantially on line 7 7 of Figure 2, parts being omitted for clearness.

The heater includes a sheet metall casing l having back and end walls 2 and 3, respectively. At the forward edge of each end wall I provide a supporting'post 4 of sheet metal secured to end wall 3 by bolts 5, or in any other suitable orl preferred manner. This post is provided at its upper end with a flared `portion forming a cup 6 which receives the body portion vof a flambeau `like container 7 having a' depending neck. 7b which fits snugly in the upper portion Yof post 4. The top or cover 7a ofthe container is provided with perforations 8, This-con tainer is adapted to contain water so as to Vprovide a certain amount of moisture, the

water being evaporated by the heat radiated' Afrom the heater, as will be understood. If desired perfumed water may be placed in the containers, but' the `principal obj ect in providing the containers isto provide simple eAreNr ortica.

and eliicient means whereby a moist heat is Y produced. Suitable foot members 9 are providedl at the lower ends of posts 4 and cooperate with similar' foot members 9a secured to a bottom plate 10 which connects end plates 3, and back plate 2, to supportthe casing.

.A front plate'll connects posts 4. This l front plate is securedby an angle strip k12 to the outer vportion of a lower reflector plate:

13 which lits snugly between endwalls 3 andf about posts 4. This reflector plate is shaped to provide two arcuate reflecting surfaces 13a which are separated by a raised element or edge 13". The inner portions of these reliecting'surfaces 132L act to reflect the heat laterally of the casing 1 thus obtaining a' unform distribution ofthe heat and also serving to heat the containerssuliiciently to cause Vaporizing of the water contained thereby for the purpose above set forth.y i

The inner edge portion of reflector plate 13 is supported upon a forwardly extending flange 14 provided at the lower edge of a supporting frame 15, this frame being provided with front and back end flanges'16 and 17,- respectively, and a back lower flange 18. The frame is, supported between end walls 3 by angle strips 19 secured tothe end `walls 3. This frame receivesa lireback 20 of refractory material, this back being pro* vvided at each end with aforwardly; projecting arm 21, the ends'of the back fitting snugly between flanges 16 and 17 of frame 15, this frame being provided with webs 22 which hold the back against lateral movemeut. Webs 22 co-operate with end lwalls 23 of frame 15 to provide dead air spaces which serve to effectually prevent heating of end walls 3 from the fireback.

The upper portion offireback 20i`s turned i downwardly and forwardly toI provide,fin4

rial which are positioned adjacent to the forward face of lireback 20 and between arms 21 of the fireback. These radiants are supported by hooks 26 carriedlbyi a dovel effect, a hood 24 for reception of the prodi ucts of combustion dischargedv from the up? 'perends of radiants 25 of refractory mate-v tailed bar 27 which its into a corresponding slot provided in the front face of fireback 20,this bar extending throughV endv walls 3 and being secured in position by caps 28 secured to the ends o f the bar in any suitable or preferred manner. A perforated plate 29 of refractory material is mounted upon the upper face of bottom plate 30 of frame l5. Plate 29 is ofv channel cross-section so as to leave a small space between this plate and plate 30, which latter plate is provided with a longitudinally extending slot for reception of the upper portion of a gas burner 3l, the burner employed being preferably that illustrated in my co-pending application 468,036; though any other suitable or preferred type of burner may be employed. The hooks 27 serve to relieve plate 29 of any pressure which might be exerted by the radiants 25, and by leaving a slight air space between plate 29 and plate 30 any possibility of warping of burner 31, due to the intense heat generated in the radiante, is elimi nated. In addition, this air space acts, to a certain extent, as a mixing chamber to insure'thorough mixing of' the gas with a maximum amount of` air so as to obtain complete combustion. Gas is supplied to burner 3l by a valve 32 of anyr suitable or preferred type which may be connected to the gas line vin any, desired manner. The products of combustion whichy are dis charged from the upper end of radiants 25 into hood 24 flow into a Hue 33 extending' through back wall 2, this flue being connected to a chimney in any suitable manner, it being understood that iireback 2Ov is provided with a suitable opening 34 to accommodate the inner end of the Hue.

Fireback 2O is further provided with a vertically extending passage or duct 35 which extends from the lower end of the ireback and for the full length 'thereof and through arms 2l. The upper portion 35"of this duct is directed rearwardly of the fireback so as to discharge air flowing through the passage 35 from the lower end thereof against a sheet metal reiiector 36 of concavo-convex crosssection and substantially semi-circular outline. rIhis reflector is rockably mounted, adjaceent to each end, on back wall 2 of the casing by means of a pintle 37 secured in sleeves 38 formed on the reflector,this pintle passing through the body of a U-shaped bracket 39 secured by ascrew 40 on the upper edge of the back plate. This bracket is provided with two angularly disposed arms 41 which are positioned at opposite sides of the reflector 36. Each of the arms receives an adjusting screw 42 which bears against a leaf spring 43 secured by means of screw 40 and nut 40,a to the opposite 'faces of bracket 39. This provides a rockable mounting for: the reL A counter-weight 44 is connected by an angle rod 45 and plate 46 to the central portion of the back of the reflector, vthis weight serving to balance the reflector so as to permit the same to be readily rocked in either direction. Plate 46 is provided with an angularly disposed arm 47 to which is secured the upper end of a coil spring 48,

the lower end of this spring being secured to t-he upper end of an operating rod 49 slidable through angle brackets 50 secured to back plate 2. The lower end ofl this rod rests upon a cam 51 secured on shaft 52 ofl a spring motor 53 positioned within the casing adjacent to back wall 2 and bottomvplate l0. A gear 54 is secured upon the other end of shaft 52 and meshes with a pinion 55 which is secured upon the shaft ofva fan or blower 56 secured to bottom plate 10. Outlet conduit 57 of the fan casing communicates with the lower end of a il-shaped manifold 58 the upper'end of which fits into the lower portion' of passage or conduit v35 of fireback20. winding rod 59 is rotatably mounted through end walls 3 and carries a bevel gear 60 secured on the rod, this gear meshing with a bevel gear 6l secured on the inner end of shaft 52. A gravity pawl 62 is mounted on the casing of spring motor 53 and engages a ratchetwheel 63 secured on shaft 52 adjacent to gear 54, the pawl and ratchet co-operating to prevent reverse rotation of the motor during winding thereof. In practice I use a motor which is capable of rotating the fan or blower 56 for a period of approximately two hours and at such a speed as to cause a comparatively large volume of air to flow through duct or passage 35 of the fireback so as to be heated thereby to a comparatively high temperaturdwhen the heater has been in operation a sufficient lengthvoftime to heat -the fireback, this heated air being discharged against the inner face of reflector 36 which is rocked slowly by cam 51 and rod 49 so as-to direct the stream of heated air alternately downwardly and upwardly thus obtaining a uniform distributionI which greatly facilitates heating of the room or apartment in which the heater is positioned. The spring 48 permits adjustment of the amplitude of rocking movement of the re- Hector without in any7 way interferingwith its operation by rod 49. To permit the iiow of gas to be regulated I provide an opening in front plate 11, this opening beingV nor'-l mally closed by door or closure plate 64 releasably secured inposition by'a spring catch 65.

When the heater is in operation, theY gas flows from burner 31 into the space between plates 31 and 29, and through the perforations of plate 29 into radiants 25 where it is ignited. The radiants become incandescent so as to generate a great amount of heat which is reflected forwardly of the heater, a certain amount of this heat being reflected laterally by means of the arcuate reflecting surfaces 13a of the plate 13 for the purpose of heating the containers 7 and also for distributing the heat laterally of the heater. In addition, the' products of combustion flowing into hood 24 serve to raise the downturned front ortion of the hood to a comparatively hig temperature which also produces a very decided heating effect supplementing the heatingeifect of the radiants. The air flowing through passage or duct 35 is heated to a high temperature and is distributed, by means of reflector 36, in the manner previously described. By construct-- ing the heater in the manner illustrated and described I obtain a maximum amount of heat for a given quantity of fuel consumed and also insure that this heat is distributed to the best advantage laterally and forwardly of the heater, a portion of the heat `generated being utilized to vaporize the water in the containers so as to obtain a moist heat which is very desirable.

I realize that it may be found desirable by experience to resort to' changes in construction and arrangement of parts of the invention, and I intend to include all such variations, as fall within the scope of the appended claims, in this application in which the preferred form only of my invention is disclosed.

What I claim is 1. In a stove of the character described,l
